Some Good news for Samurai Battles, according to Richard Borg on Boardgame Geek, GMT will pick up/expend the game. Not clear what is coming, but it has to be better than the alternatives.
Re: Regarding need to expand Samurai Battles and Ninja Attack
As the saying goes... WAIT FOR IT!!!!
GMT is already on this and will be leading the charge soon!
